What is the purpose of adjusting arcs of variable arc nozzles during an irrigation system audit?

• A. To Enhance Water Pressure
• B. To Prevent Overspray
• C. To Increase Water Efficiency
• D. To Schedule Timings

Answer: (B)

The purpose of adjusting arcs of variable arc nozzles during an irrigation system audit is primarily to prevent overspray. When the arcs of nozzles are accurately adjusted, the water is directed more precisely to the targeted areas of the landscape, reducing the likelihood of water being wasted on unintended surfaces such as sidewalks, driveways, or other non-irrigated areas.

This adjustment helps to ensure that the water is effectively reaching the plants and soil where it is needed most without creating excess runoff or over-saturating certain patches. Consequently, preventing overspray not only conserves water but also improves the overall efficiency of the irrigation system, leading to healthier plants and a more sustainable landscape approach.

While increasing water efficiency is an important goal of irrigation audits, it directly correlates to preventing overspray, as effective water delivery minimizes waste. The other choices, such as enhancing water pressure or scheduling timings, do not specifically relate to the adjustment of the arcs, making those options less relevant in the context of the nozzles' purpose.
